<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >

    <gradient
        android:angle="90"
        android:centerColor="#555994"
        android:endColor="#b5b6d2"
        android:startColor="#555994"
        android:type="linear" />

    <corners 
        android:radius="0dp"/>

</shape>

if you want to draw it through shape you have to do work with layer-list. You can think about it like two rectangles and every rectangle has its own gradient color.
